Abstract
We identified newly discovered pamphiliid larvae feeding on Cornus in Tochigi and Ibaraki Prefectures, Honshu, Japan, with Pamphilius japonicus Shinohara, 1985, by molecular methods using mitochondrial cytochrome oxidase subunit 1 (COI) gene sequences. The host plant of P. japonicus was unknown. This is the first record of the Cornaceae as a host plant of the Pamphiliidae in the Old World. The larvae were solitary leaf-rollers on Cornus and discovered mainly on small young trees in shadowy forests.
